Spring RestTemplate throws IllegalArgumentException: not a valid HTTP URL

Question

java.lang.IllegalArgumentException: [https://localhost/pcap/search?stime=20110930%2E000000&etime=20110930%2E235959&bpf=tcp

Here is the call I made using Spring RestFul Template:

final PcapSearchResponse pcapSearchResult = restTemplate.postForObject(
    nPulseApiUris.get(2), null, PcapSearchResponse.class, sTime, eTime, bpf);

I don't understand why that is a bad URL? I used UTF-8 to encode the "." character but I am not sure why my URL is still invalid.

Your help is greatly appreciated!

Thank you for your help!!!

The documentation of RestTemplate mentions that:

Furthermore, the String-argument methods assume that the URL String is unencoded.

So, when passing your URL as string, don't encode it. Spring will take care of that.

Hi Bozho, thank you very much for your response. Yes I did not encode the url. The URL looks like the following in my code in which the nPulseApiUris is of type List<String>: https://localhost/pcap/search?stime={stime}&etime=${etime}&bpf=${bpf} Your help is greatly appreciated!

If I get rid of the ampersand, I'm not sure how I'm going to post those parameters to the RESTful service URI. Hence I thought if I append it, that would work. Thank you for your help!!

Don't remove the whole amperasnd, but don't write it encoded. So & instead of &
